HESI A2 Vocabulary 2023

Correct Answer: A

Rationale: The correct answer is A: Ripple. In this sentence, 'undulate' is used to describe a smooth, wave-like motion of the muscles, which aligns with the meaning of 'ripple.' The word 'undulate' implies a continuous and flowing movement, resembling the gentle and rhythmic movement of waves. The other choices, shake, flatten, and unknot, do not capture the specific fluid and continuous motion described in the sentence. 'Shake' implies a more abrupt and irregular movement, 'flatten' suggests a completely different action of making something flat, and 'unknot' refers to the action of undoing a knot, none of which fit the context of the sentence.

Correct Answer: B

Rationale: The correct answer is B: Drooping or loose. Flaccid means lacking firmness or stiffness, often used to describe something that is limp or lacking in strength or vigor. In this context, flaccid refers to something that is drooping or loose. Choice A is incorrect as light-colored does not relate to the definition of flaccid. Choice C is incorrect as uncontaminated is not a synonym of flaccid. Choice D is incorrect as unusually aggressive is unrelated to the meaning of flaccid.

Correct Answer: D

Rationale: The correct answer is D: Commotion. In the given sentence, 'tumult' is used to describe a state of confusion and disorder in the emergency room. A commotion refers to a noisy disturbance or uproar, which perfectly fits the context of the sentence. Siren (A) refers to a loud noise, not the overall chaotic situation. Distress (B) and suffering (C) are related to feelings of pain or discomfort, but they do not capture the sense of chaos and noise implied by 'tumult' in this context.

Correct Answer: D

Rationale: The correct answer is D: Bond. Rapport refers to a close and harmonious relationship or connection between individuals. In the context of the sentence, 'developed a quick rapport' implies that the nurses and teenage aides quickly formed a close bond or connection. This is evident through their ability to communicate effectively, trust each other, and work well together. Choice A: Performance is incorrect because rapport does not refer to performance but rather the relationship between individuals. Choice B: Narrative is incorrect because rapport does not relate to storytelling but rather the bond or connection between people. Choice C: Manner is incorrect because rapport is not about the way something is done but rather the quality of the relationship. In summary, the word 'rapport' in this sentence specifically means a bond or connection between the nurses and teenage aides, making choice D the correct answer.

Correct Answer: C

Rationale: The correct answer is C: To dispute the truth of. Impugn means to challenge the validity or truthfulness of something. This is the correct answer because impugning involves questioning or casting doubt on the credibility of a statement or claim. A: To instill with - This choice is incorrect because instill means to introduce gradually, which is not related to the meaning of impugn. B: To instruct about - This choice is incorrect because instruct means to teach or provide information, not to challenge the truth of something. D: To lament or complain about - This choice is incorrect because lamenting or complaining is about expressing sorrow or dissatisfaction, not about disputing the truth of something.
